THOMAS OLINGER AND JOHN L. nu ornorrun, 6550mm MICHIGAN. AssIGNons TO FEDERAL SIAMPING COMPANY, or O L MICHIGAN, agconrorm'rroiv. or

MICHIGAN.

Be it knownthat we, "THOMAS and JOHN L. DE GLOPPER, citizens of the United states otAmerica, residing at" H01 land,'in the county of Ottawa and State of Michigan, have invented certain new and useful Improvements in Furnace-Damper Reg ulators; and we do hereby declare the follow; ing to be a make and use the same. v

This invention relates to a novel construction of furnace damper regulator. Regulators of this Character are located in an upper room of a dwellinghouse or otherbuild- 7 mg I one being hingedly mounted in connection with the smoke 'pipe a short distance from the furnace, and the other being hingedly mounted on the door Which closes thefront of the ash pit. It is'desirable that these dampers may be regulated together so that one may similaropening of the other and vice versa.

With our invention, a particularly simple,"

yet durable and eflicient furnace regulator is made,

1 the parts except the chain usedwith the regulator are of readily blanked and formed from 'sheet metal with dies. There are but three parts to the structure. It is a primary object and purpose of the invention to producea fur nace regulator which is not only very s mple in structure, containing a minimum number of parts wlth a resultant low cost otmanufacture, but one whlch from itsiconstruction has inherent durability such-that its effec-:

tive life under usual service is practically indefinite A further object of the invention is to make a furnace regulator of parts easily assembled and so constructed that the chain associated therewith'may be readily connected either before or after the parts are H in assembled relation or, if desired, may-be changed as to position as readily in the com- 'plete assembled structure. still further --object;of the invention is to provide a novel of the invention, such as will enable othersskilled in the art to which it appertains t9- be more or less' closed with the and at a'relatively low cost.

manner of attaining a frictional I engagement between the relatively stationary memberwof the regulatorand the movable j'c'hain' actuating member thereof such that" the movable member will stay inany'position to which it may be movedi'or agreater or'less opening or closing of the check lan'ddratt dampers. All of theseteatures, together wlth many others not at-this"time;specifi-' cally enumerated" will appear fully and in detail as understanding of the invention is had'trom the following description, taken in connection with the accompanying drawing,- inwhichz Figure 1 is an elevation of the regulator.

In the c'onstruction of the regulator,: an

outer supportingfmember of sheet metal is -usedi,i comprising-a -substantiallycircular face lat theouter edges otiwhichan outtancefimakingf a continuous annular slide 3, from wlncha flange4-1s turned outwardly,

wardly extending beadfQ-is' formed,from whichthe metal' extendsbackward. for a disthe same being formed at 7 itsupper and lower pointswith projectingears 5 through whlchscrews or equivalent fastening means may passv to' connect the support "and the parts carried'thereby to the side of a wall or' other stationary support in the room where thefregulator isiinstalled; relatively long 1 andnarrow" slot 6 is cut in'the side 3 at the -=upper partthereof forsubstantially half of the length of said side. Below each end of the slot, an opening 7 is made in the side 3 for the passage of the chain. Centrally of the face 1 an opening is made and the metal pressed to the rear to make a cylindrical hub 8 the purpose of which willlater appear.

This outerv Supporting member constitutes V a housing within which the chain actuating member is mounted. Said member is similar to the outer member in construction many respects, comprising an outer face'9 through which a central open'inglO is made,

an outwardly formed bead 11 at the outer edges of the face 9 a rearwardly extending continuous annular side 12 and a flange 13 turned outwardly therefrom. A short slotl f is cut through the upper side of the, side 12. andat the same side of the actuating member the flange 13 is cut away as indicated at 15 to leave a projecting tang 16 as shown in Fig. 7 v

The third member of the regulator is the operating handle. This handle is formed from a fiat piece of sheet metal 17 through which at its lower end an opening 18 is made. Adjacent its upper end the handle is narrowed as indicated at 19 and two cars 20 turned forwardly therefromso that in the assembled regulator the same project in front ofthe outer supporting member as shown in Fig. 4..

The chain actuating member in formingthe same has its face 9 dishedrearwardly as shown in Fig. *5. In the assembly, the chain actuating member is placed within the outer member with-its bead 11 bear-' ing against the rear side of the face 1 of the outer supporting member. The dished face 9 of the chain actuating member is pressed substantially flat so that the hub 8 passes through the-opening 10 in face 9. The operating-handle is passed through slots 6 and 1 1 and the hub 8 passed through the opening 18 therein, after which theend of thechub is pressed outwardly to make a se-- curing flange 21 which permanently secures the three parts of the regulator together. It is evident that the normal tendency of the dished face 9 of the chain actuating member to return to its original position causes the bead at 11 to press with considerable pressure against the rear-sideof the face 1 of the-outer member, making a frictional engagement which holds the parts in any positionwhich they may take or to which they, maybe moved with respect to I each other. The chain 22 is placed around thepinner chain actuating member before.

assembly, ordinarily, the tang 16 being passed through one of the chain links and the ends of the chain being carried through openings? when the chain actuating member is placed inside the outer supporting member. It is obvious that one end of the chain leads to the'check damper and the other to the draft damper as is usual in fur nace regulators.

This construction of furnace regulator comprises but three pieces, all readily stamped and'formed from sheet metal and easily assembled. T-he frictional engage-w ment of the chain actuating member with the outer supporting member is firmand -where' the-furnace isinstalled. The large frictional bearing surface insures against undue wear and gives an exceptlonally, long I life to the regulator. In fact, an attempted.

destructive test of this regulator byoper-J I ationt-hereof through sufficient number of movements to comprehend fifteenyearsordi-' nary ,se'rvlce shows no change 1n. the regulator 1n any respect. Economy. of manu-.-

facture, a minimum number of parts, e'x;' ceptional durability, and simplicity of con' struction, all combineto make the regulator one of value and merit.

It'will be notedthatthefla'nge 13 in the assembled regulator extends, nearly to the side of the outer member, renderingv it im- 1 possible for the chain to escape from the chain actuating memben By bending the I tang 16 outwardly, however, the chain may be detached and removed from its actuating member. It is also possible to thread the chain through an opening 7 Y and connect it withthe tang, after which it may be carried by turning the chain actuating member to the other opening-7. for passage therethrough, making it possible to easily thread the chain through the regulator should it ever be necessary after'the parts are assem- Y .110

bled. These possibilities in connection with the furnace regulator add to its practical value as is evident. 'Z
